Clamp for liquid meters



Patented Dec. 5, i922 lABlQt? GIJAMP LIQUID Application filed June 1;

State oillew York, have inven certain new and useful improvements in &JHPS for Liquid Meters, of which the toll specification T This inventionrelates to liquid me: and is particularly directed to the prorit of afrost-proof olanip for devicesot this nature. i r 4 c Une of theprincipal objects of the lIiWl'ltion to provide a frost-proof clamp forholding the upper and lower members oi lquid meters such as those shownin my copending. applications Serial Nos. 383,265 and 4103,0852.

Another object is to provide e clamp ot this nature which shall possesssufficient strength tohold the members of the meter in sealingengagement under the me? mum service pressures. p

rinothe'r object is to provide a clamp or this nature which shall besuitably weilrcoed and assembled so that excessive pr v, re abovemaximum service pressure will effect breaking of the clamp, therebyrelieving pressure in the meter resnlt' from freesing of the liquichthus providing; a trost-- proof meter. I iinother object is to produce aclamp that shall be simple of constructioin inexpensive tomanufacture,and highly e'ilicient for purpose for which it is designed:

Another object is to provide clamps tor the meter of unitormcconstruction so that the same may he interchangeable thus facilitating;manufacture and replacement oi broken parts. i

Another object is to provide device of this nature in which no machiningor parts is required.

Another object is to effect an equal pressure about the flanges of themeter, exerting pressure at a number of equally spaced points and usingonly asmall number of bolts.

Another object is to produce a device which is simple and facile ofmanipulation so as to permit easy access to the meter for inspection orother purposes.

Another object is to provide a device such as to permit the use ofproper materials for the various parts, thus bronze may be used m1.'Seria]. no. M4 249.

for the meter body and cast iron for the clamps. i a

Another object isto produce a clamp in which one of themembers weakenedso as to be more easily broke n and to git e when subjected topredetermined pressure thus avoiding distortion olf the other parts ofthe meter and clamp. i

l Vith these and other objects in view, which will he more, apparent asthe specl. tion proceeds, the invention resides in cer? tain novelconstruction end combination and arrangement of parts the essentialfeatures of which. are hereinafter fully described are particularlypointed out in the appended claims, and are illustrated in the facco1npanyin r drawing;- in which l i re 1 is a side elevation with one clampshowing and another removed.

These lugs are equal y SPQCQ'Tl apart around the-entireflanges so that when the clamps are applied thereto, an even and suh stantially uniform pressnreis obtained at all points of the flanges I jEach clamp comprises iourjmemhers, a boltltl having a head 17, a nut 18,an upper jaw or clamp'memberlll, and a lower jaw or clamp member20. Theupper jaw 19 has a horizontal portion provided with two conical seats 21for receiving two adjacent ones of the conical lugs 14 of the flange 12]This member also includes a depending portion 22 -tormedat its center toprovidea shroud 23 for the bolt 16. The lower surface of shroud 23 isprovided with a downwardly extendingfinger 2e.

The lower jaw 20 is provided in its upper face with two conical seats 25for receiving of a liquid as attached inner elevational view of use! twoadjacent ones of the conical lugs 15 of the flanges 13, and with a seat-17 for the end of finger 24. The lower face of j aw 20 is provided witha pair of fingers 27 which coact with the head 17 of the bolt 16 toprevent turning when screwing down the nut 18. Between the fingers 27 isa weakening notch 28 which determines the point of breakage of themember 20 when excessive strain is applied. Members 19 and 20 aresuitably curved throughout to conform with the contour of the meterbody.

lVhile I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedwithout in any way departing from the spirit ofmy invention, and Itherefore do not limit myself to the exact details of constructionherein set forth nor to anything less than the whole of my inventionlimited only by the appended claims.

What is claimed as new is 1. In a device of the class described, thecombination of a meter body comprising separable members; lugs formed onsaid members; a pair of jaws, each co-acting with a plurality of saidlugs of a respective one of said members; and means for securing saidiaws in "operative relation tosaid lugs.

2. In a device of the class describes, the combination of a liquid meterbody comprising separable members, mating flanges formed on saidmembers, equally spaced conical lugs formed on said flanges andextending in opposite directions, mating clamp members each providedwith conical seats for engaging lugs of respective flanges, and a boltfor drawing said clamp members together to effect a seal of said meterbody.

3. In a device of the class described, the combination of a liquid meterbody comprising separable members, mating flanges formed on saidmembers, equally spaced conical lugs formed on said flanges and er.-tending in opposite directions, nating clamp members each provided withconical seats for engaging lugs of respective flanges. one of said clampmembers being formed with a weakening notch, and a bolt for draw- 'ingsaid clamp members togetherto effect a seal of said meter body.

4.. In a device of the class described, the combination of a liquidmeter body compris conical lugs formed on said flanges and eX- tendingin opposite directions, mating clamp members each provided with conicalseats tor engaging lugs of respective flanges, and a bolt for drawingsaid clamp members together to effect a seal of said meter body, one ofsaid clamp members being provided. with a shroud for said bolt.

6. In a device of the class described, the combination of a liquid meterbody comprising separable members, mating flanges formed on saidmembers, equally spaced conical lugs formed on said flanges and eX-tending in opposite directions, mating clamp members each provided withconical seats for engaging lugs of respective flanges, and a bolt fordrawing said clamp members together to'eliect a seal of said meter body,one of said clamp members being provided with a pair of fingers forholding said bolt against turning, said fingers defining a weakeningnotch.

'Z. A clamp comprising a bolt and a pair of jaw members, each of said awmembers being provided with a plurality of conical seats, one of saidjaw members being formed with a shroud for said bolt, said jaw membersbeing provided with co-acting interfitting elements, and one of said jawmembers being provided with means for preventing turning of said bolt,said means defining weakening notch as and for the purpose set forth.
